IMPROVEMENT IN MACHINES FOR FOLDING AND PASTING COLLAR ENDS.

Specification forming part of Letters Patent No. 116L833, dated April 6,1875; application filed December 5, 1874.

To all whom it may concern:

Be it known that I, CHARLES SPoFFoRD, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a certain new anduseful Improvement in Machinery for Folding and Pasting the Ends ofCollars or other articles, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in whichFigure l is a plan View of a machine containing my invention. Fig. 2 isan inverted view thereof. Fig. 3 is a vertical section in the plane ofthe line a." w of Fig. 2. Fig. 4. is an end view, detached, of one ofthe folders T t. Fig. 5 represents a collar which has passed through themachine, its ends w being folded and secured to the inner side of thebody of the collar.

Similar letters indicate corresponding parts.

The object of this invention is to fold and paste the ends of collarsmade of paper, or paper and cloth combined and it consists in a carryingdevice which carries the collars, separately, over a suitablesupporting-table to a pasting device or devices, which apply a properquantity of paste or suitable adhesive substance to the inside of thecollar, at the place where it is to be folded and fastened down, andthen to a folding device or devices, which folds or bends the ends at aright angle to the plane of the collar, and next to a folding devicewhich completes the fold and brings the bent ends up to or parallel withthe body of the collar, after which the collar is carried along tocompressing-rollers, which compress the bent parts against the collars,and discharge the collars from the machine.

Theletter A designates a frame, which supports the table A, over whichthe collars are carried, and also the other parts of the machine. Theletter B designates a drivingshaft, having hearings in the rear end ofthe frame, which shaft is provided with bevelgears O O, that engagebevel-gears D D, which are secured 011 the adjacent ends of shafts E E,which carry the revolving folding devices that act on the collars. Uponthe shaft B are also arranged compressing rollers, or surfaces F F,which act in conjunction with like rollers or surfaces F F, on an uppercounter-shaft, B, to receive the folded collars from the car riers andcompress the bent and pasted parts against the body of the collar.

The rollers or surfaces F and F are arranged upon their shafts, so thatthey only act on that part of the collar where the bent parts are foldedagainst it, and the upper shaft B is journaled in sliding hearings inthe frame directly over the main shaft B, and is held down upon thatshaft by spring-pressure, or by gravity, so that its roller-surfaces Fwill be pressed against the roller-surfaces F of the the lower shaftwith sufficient yielding pressure to unite the folded ends to the bodyof the collar, the shaft B rising in its bearings to allow a collar topass.

The counter-shaft B is driven from the shaft Bvby elastic belts G G,orother devices which will permit it to rise in its bearings. Thedriving-shaft B is provided with a pulley, H, that receives a chain orbelt, I, which drives the paster-shaft J, which is arranged under thetable of the machine, as is shown in Fig. 2. The shaft B is alsoprovided with pulleys H H, arranged near to and inside of theroller-surfaces F, which pulleys receive the carrier chains or belts KK, that are carried around pulleys L L, fixed upon a counter-shaftarranged in the front part of the machine. The chains or belts K areprovided with horns M, which project outward therefrom, and are arrangedabout the width of a collar apart from each other. The paster-shaft J isprovided toward its ends with double segments N N, which are fixed onthat shaft, and which, in their revolution, work against and are chargedwith paste from paste-rollers O O, that are mounted loosely inpaste-troughs P P, arranged in proper positions under the table.

The paste-rollers O are caused to revolve in their troughs by thecontact of the segments N, whose peripheries work through slots Q in thetable A, and apply the paste or other adhesive substance which adheresto them to the under side of the collar, at the parts which are to befolded, the direction of their revolution coinciding with the directionof motion of the collars. The table A is surmounted by aconfining-frame, It, which is suspended over itat a sufficient height toallow a collar to pass flatwise between them. The frame R is suspendedfrom cross-bars S S, one of which provides bearings for the front endsof the folder-shafts E E, before mentioned. The frame R serves to keepthe collars extended and flat upon the table while they are passingthrough the machine. After the collars have passed over thepasting-segments N, they are carried to the revolving folders T, whichbend down the ends of the collars in the slots Q. The folders T aremounted in such a manner as to intersect the slots Q, and they revolvein a plane perpendicular, or nearly so, to the path of the collars, andthey consist of segmental blades t t, of triangular form, whose frontedges 25 come down upon the ends of the collar and bend them over theedges S of the slots Q, the inclined sides U of the folders (which sidesanswer to the hypotenuse of the triangle) retiring, as it were, andallowing the ends of the band of the collar to advance without strikingthe folder, so that the folders are free to operate on the ends of thecollar without touching the band. After the collar has passed thefolders T it is carried to folding-guides V V, which consist of spiralchannels formed in the table A, commencing at the rear end of the slotsQ, and terminating at the rear end of the table, in front of therevolving compressing-surfaces F F. The folders V are so formed thatthey receive the bent ends of the collars from the slots Q, andgradually turn them toward the plane of the body of the collar, so thatwhen the collars emerge from the folders V the bent ends are flat andparallel with the rest of the collar, and they then pass between thecompressors F F, which press the bent ends against the body of thecollar, and enable thepaste or adhesive substance which had-beenapplied, as before stated, to cement and secure the folded ends fast tothe body of the collar. The horns of the carryingchains are so spaced,and the pasters N and the revolving folders T are so made and arranged,that the ends or parts of the collar to be pasted and folded will bepresented to the pasters and folders at the proper times.

In this illustration of my invention it is intended thatthe collar belaid with its inner side down, so that the inner side of the ends shallreceive the adhesive substance.

In Fig. 5 I have represented a collar having its ends folded and pastedto the body of the collar. The ends of the bands X X, Fig. 5, extendover the slots Q and over the table of the machine, while the collar ispassing through the machine, and when they are opposite the revolvingfolders T the bands pass through the curved openings Y, between thesegments t t, and avoid contact with the folders, the openings Yoccurring between the pointed end of one segment and the front edge ofthe next.

My improvement is applicable to other articles which are capable ofbeing folded or cemented, and is not confined in its application tocollars only.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a machine for folding and pasting the ends ofcollars or other articles, of a carrying-table, A, carrying-chains K,pasters N, revolving folders T, folding guides V, and compressingrollers, substantially asdescribed.

2. The combination of the table A, confining-frame B, revolving foldersT, and pasters N, and carrying-chains, substantially as described.

3. The revolving folder T, provided with a folding device, It, one ormore, having an angular or retiring side, U, arranged substantially asset forth, so that the folders can operate without touching the bandends of the advancing collar.

4.. The revolving folder ,T, constructed with one or more foldingdevices, t, in combination with the table, having a slot, Q, and afoldingguide, substantially as and for the purpose specified.

5. The combination of the pasting device N and folding devices T t V,with the roller compressing devices F F, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 18th day of November, 1874..
